Which behavior is appropriate when using public Wi-Fi networks?

Using a virtual private network (VPN) is an appropriate behavior when using public Wi-Fi networks because it adds a layer of security to your internet connection. Public Wi-Fi networks are often unsecured, making it relatively easy for cybercriminals to intercept data being transmitted over these networks. A VPN encrypts your internet traffic, protecting sensitive information from being accessed by unauthorized individuals and helping to safeguard your privacy.

In contrast, conducting sensitive transactions without caution poses significant risks as it exposes personal information and credentials while using a public connection. Disabling your firewall compromises your device's security, making it more vulnerable to attacks and unauthorized access. Accessing a company's internal resources directly from a public Wi-Fi network without secure measures, like a VPN, could lead to data breaches or unauthorized access to sensitive organizational information. Thus, utilizing a VPN is a recommended practice to enhance security in these risky environments.
